The logo of the 1984 Los Angeles Olympics includes red, white and blue stars, but the white star is not really there: It is an illusion. Similarly, the “S” in the USA Network logo is wholly illusory.

Both of these logos take advantage of a common perceptual illusion where the brain, when viewing a fragmented background, frequently sees shapes and surfaces that don’t really exist.
